Abstract
A hand-held machine tool, in particular a sanding machine, including a rod-type handle element for the user to grip and a processing head which is moveably mounted on the handle element by means of a joint assembly. The processing head has an electric drive motor for driving a tool holder provided for holding a processing tool and a speed-reducing gearbox between the drive motor and the tool holder, the gearbox being designed to achieve a reduction in speed of an output of the drive motor relative to a speed of the tool holder. The drive motor is a brushless motor and a power supply system for the drive motor is arranged at a distance from the drive motor on the handle element, the power supply system being connected to the drive motor by means of a cable arrangement.
